So I have this stored procedure in SQL server that has this bit of SQL in it
... part of store procedure...
IF @@ERROR = 0 --AND @@ROWCOUNT = 1
BEGIN
.. dO STUFF
SELECT * FROM MyTable
RETURN 0
END
ELSE
BEGIN
RAISERROR('Something went wrong :-(', 16, 1)
RETURN -1
END
END
in my C# code where I get the data I do it like this
//Sql param used to get the return value from the store procedure
SqlParameter returnValueParam = command.Parameters.Add("@return_value", SqlDbType.Int);
returnValueParam.Direction = ParameterDirection.ReturnValue;
using (var reader = command.ExecuteReader(CommandBehavior.CloseConnection))
{
while (reader.Read())
{
SpRetrunValue.EmailAddress = DBNulls.DBNullToString(reader["Email"], string.Empty);
... More stuff
}
reader.NextResult();
SpRetrunValue.ExternalData = new List<ExternalData>();
var ExtData = new ExternalData();
while (reader.Read())
{
ExtData.Id = DBNulls.DBNullToInteger(reader["ID"], 0);
SpRetrunValue.ExternalData.Add(intExtData);
}
//get the return code on the SP 0 for success -1 for error
SpRetrunValue.ResultCode = (int)returnValueParam.Value;
}
the problem I am having is that if I use it with command.ExecuteNonQuery(); then I can get the return value. But using as is now I can not get the return value, but I do get the result set. Is it not possible to get the return value this way? I have seen this post here on stackoverflow, but that requires me adding another param to the stored procedure, which I feel defeats the purpose of just returning a value like in my stored procedure above.
